Specification of Letters Patent. Patntdl DB6. 114i, llgllli Application filed October 30, 1914i. Serial No. 869,362.

To all wlw/t n; may concern:

. Be it known that we, ViTAL'rnn DRABOLD and ArGsTUs P. Murr, citizens `of the United States of America, residing atA Detroit, in the county of Wayne and State of Michigan, Lhave invented certain new and useful Improvements in Automobile Traffic- Signals, of which the following is a specilicatiom-reference being had therein to the accompanying drawings.

This invention relates to automobile trailic signals, and the principal object of our invention is to provide a sernaphorical signal which will indicate by day, as well as by night7 to oncoming vehicles, the fact that the signal carrying vehicle is about to stop, reduce speed, or turn into another lane of travel.

Another object of our invention is to provide a. novel bracket andclamp by which the signal can be easily and quickly connected to a vehicle spring.

A still further object of our invention is to provide a semaphorical signal that is automatically actuated when vehicle brakes are applied, thereby relieving the operator or'chauifeur of a vehicle of the responsibild ity of operating the signal.

The above and additional objects are aca complished by a device that will be herein-- after specifically vdescribed and claimed, and reference will now be had to the drawing, wherein Figure 1 is a side elevation of a portion of an automobile'provided with ya signal in accordance with our invention; Fig. 2 is a front elevation of the signal partly broken away and partly in sections; F ig. 3 is a side elevation of the saine, partly in section, and- Fig. 4 is a perspective view of a bracket and clamp constituting means for connecting'the signal to a Spring or other support.

. The signal comprises a tubular post or cylinder 1 having the ends thereof eXteriorly screwthreaded, as at 2 and detachably mounted upon the upper end of the post or cylinder is a cap 3 provided with a' depending vsocket 4 for an incandescent lamp 5, said lamp having electrical connections 6 eX- .tending through an opening 7 provided therefor in the post or cylinder. The electrical connections 6 are connected to a suitable'source 4of electrical energy as batteries, carried by a vehicle. The incandescent lamp 5 constitutes illuminating means for the sig` nal and the front side of the post or cyli1lthen der has an opening il closed by a transparent plate S) to exclude-dirtand foreign matter from the interior ofthe post or cylinder. The side of the post or cylinder has another opening 10 closed by agtransparent plate 11, and this plate allows rays of light to be cast upon a license card or sign 12 connected to a holder 1B clamped upon the up per end of the post or cylinder. Another band or holder le is clamped upon the post or cylinderand affords a bearing 15 fory a. semaphore arm 16. The semaphore arm 16 has the innerend thereof provided with an apertured extension 17 that protrudes through a slot 18 in the side of the post or cylinder and said apertured extension is connected by a rod 19 to the crank 20 of a rock shaft 21. The rock shaft 21 is jour-- naled in suitable bearings 22 provided therefoi-'in the lower end of the post or cylinder and one end of said rock shaft has a crank 23 connected by a rod or cable 24 to a brake element 25 of an automobile 26. The apertured extension 17 is connected by a coiled retractile spring 27 to a wall of the post or cylinder, said spring preventing vibrations vof the vehicle when in motion from shifting the semaphore arm 16.

Suitably connected to the front side of the semaphore arm 16, as at 28, is an angle bracket 29 terminating in a segment shaped llens holder 30, said holder having red and for the plate or bracket 32 a yoke 34 is employed, said yoke embracing the spring and having the ends thereof .extending through vthe plate 32 and provided with nuts 35. To

correctly position theplate 32 and prevent accidental displacement of the same due to any action of the spring-33 an angularly disposed screw 36 is mounted in the plate or bracket 32 to engage the spring 33 and cooperate with the yoke 34C in supporting the plate or bracket in substantially a horizontal plane. 'The screw 86 is adjustably mounted in an angularly disposed opening 37 provided therefor in an extension 38 of the plate or bracket, as best shown in Fig. fl:

and it is through the medium of this adjustable screw that the post or cylinder is retained in ..a vertical position contiguous to the rear end of the automobile body, Without interfering with tire supports or other automobile accessories.

During the day the semaphore arm 16, when raised, indicates change of direction in travel or acessation in the operation of the automobile and at night, va green light is displayed and normally indicates safety or caution, but should there be a change 1n the operation of the'automobile necessitating an application of the brake, the semaphore arm 16 is immediately raised and the red lens or bulls-eye shifted in front of the illuminating means of the signal to indicate danger.

The license card 12 and the holder thereof can be dispensed with in some instances and (topics of this patent' may be olitained for the entire device finished to harmonize with the fittings of an automobile.

Vhat we claim is z- In a semaphoric signal for automobiles, the combination with a rear spring, of a bracket clamped thereon, adjustable means carried by said bracket and engaging said spring for positioning said bracket in a substantially horizontal plane, a post carried by said bracket, a. visible signal at the upper end of said post, and means operatable at the lower end of said post for moving said signal.

In testimony whereof We aiix our signatures in presence of two Witnesses.
